Instrument: Large Aggregate Profiling System

The Large Aggregate Profiling System (LAPS) is a camera system developed to characterize millimeter size particle distributions in the water column. Camera systems are integrated with a CTD and transmissometer and therefore have the advantage of simultaneously collecting data on the distribution of suspended particles and aggregates along with the physical structure of the water column (Honjo et al., 1984; Asper, 1987; Gardner et al., 1988).
